Hi Old Smokey....Did you ever have a dead engine with a windmilling prop ?????
I can assure you that that pitch control becomes totally useless, experienced myself back in 1993 in my Cap21.....And believe me the engine will not seize, unless there is no oil.
But right the thread is about windmilling props, with an aerobatic plane three blade prop pulling back throttle, and pitch to fine will throw you forward like an airbrake; The rate of descent if you do not reapply power will go to the variometer bottom stop.
